From Revolution Design:
The RDRP Battery Plate Thumb Nuts for Team Associated 5th generation off-road vehicles are machined from high-quality 7075-T6 aluminum and they are of a super lightweight design while offering a slightly lower profile than the original ones. Excessive machining brings then down to 0.8g per piece while their overall design makes them looking gorgeous in your ride. Included with the thumb nuts come clear O-rings to prevent them from becoming loose in severe off-road action. The thumb nuts are available in blue or black anodizing to match with the remainder of Revolution Design Racing Product’s option parts for AE 5th generation cars.
